2007 BMW X3 “Despite the high expectations that come with attaching the flying propeller logo to any vehicle, the new X3 still surprises those expectations with amazing prowess.” — Edmunds.com See More Reviews

2007 Land Rover LR3 “Touted as the Discovery replacement, the LR3 continues to live by Land Rover's outdoor off-road creed, but this vehicle has been optimized for on-road driving as well.” — Edmunds.com See More Reviews

2007 Land Rover Range Rover Sport “Immediately after a heavy downpour that created some very slick and slimy conditions on a horse farm outside Chicago, all that was required of our British ute was to throw the transmission lever into "Low," twist the Terrain Response dial (located on the console between the front seats) one click to the right (Grass/Gravel/Snow), and we were on our way. A little throttle modulation and steering input were all the driver had to worry about. Simple.” — Road & Track See More Reviews

Autos.com editors have compiled the most extensive rating database on the internet, drawing upon $20 million of automotive research from CarsDirect and Autodata, and summarizing expert opinion from an extensive group of the leading third party sources. Here is a brief overview of how we do it:

Professional Reviews Ranking: Autos.com editors analyze car reviews from a range of magazines and websites, distill each down to a quantifiable ranking and then average those rankings to arrive at the Professional Review Rank.

Other Rankings: Autos.com also ranks vehicles based on criteria such as fuel efficiency, cargo capacity, and comfort and convenience features. You can see some of the data that we have used to rate each vehicle in any given category by expanding the category header on the vehicle detail page. For example, click on the arrow next to "Passenger Space" on the Honda Civic detail page to see the actual measurements for that vehicle's interior. These measurements were stacked up against the interior measurements of all the other vehicles in the compact car segment in order to calculate the Honda Civic's rating in the Passenger Space category. That rating is then used to determine the Honda Civic's overall ranking in the compact car category.
